If your getting over run with MTS then your overfeeding your tank. I have them in all my freshwater tanks 2.5g to 40 breeder, haven't had any out of control population explosions, so far the only snail explosion I had was from mystery snails awhile back which was probably from me overfeeding.

I use a hose a bit bigger then an airline hose and hover it about 1" above my sand it sucks up any debris and leaves the sand alone.

I really like RCS. It is very cute when they trundle about on the sand snatching little bits of food. That being said, if you have light-coloured sand, their poo shows up like crazy. I vaccuum my tank everyday just so it doesn't look grotty.

well at this point I have moved the snail out of one of my 3 boy's tanks & moved a ghost shrimp into it.. Was done simply that the betta sam (in my avatar) constantly acts weird.. he try's to buy himself under whatever he can. I would put in hiding spots & he instead of using them still tries to bury himself in the gravel. I Wanted to see if he would take to shrimp any better then the snail.
